useDelete

useDelete is an extended version of TanStack Query's useMutation. It supports all the features of useMutation and adds some extra features.

• It uses the deleteOne method as the mutation function from the dataProvider which is passed to <Refine>.

It is useful when you want to update a record.

Basic Usage

The useDelete hook returns many useful properties and methods. One of them is the mutate method which expects resource and id as parameters. These parameters will be passed to the deleteOne method from the dataProvider as parameters.

import { useDelete } from "@refinedev/core";

const { mutate } = useDelete();

mutate({
    resource: "products",
    id: 1,
});

Realtime Updates

This feature is only available if you use a Live Provider.

When the useDelete mutation runs successfully, it will call the publish method from liveProvider with some parameters such as channel, type etc. It is useful when you want to publish the changes to the subscribers on the client side.

Refer to the liveProvider documentation for more information →

Invalidating Queries

When the useDelete mutation runs successfully, by default it will invalidate the following queries from the current resource: "list" and "many". That means, if you use useList or useMany hooks on the same page, they will refetch the data after the mutation is completed. You can change this behavior by passing invalidates prop.

Refer to the query invalidation documentation for more information →

Audit Logs

This feature is only available if you use a Audit Log Provider.

When the useDelete mutation runs successfully, it will call the log method from auditLogProvider with some parameters such as resource, action, data, previousData etc. It is useful when you want to log the changes to the database.

Refer to the auditLogProvider documentation for more information →

Properties

mutationOptions

mutationOptions is used to pass options to the useMutation hook. It is useful when you want to pass additional options to the useMutation hook.

Refer to the useMutation documentation for more information →

useDelete({
    mutationOptions: {
        retry: 3,
    },
});

tip

mutationOptions does not support onSuccess and onError props because they override the default onSuccess and onError functions. If you want to use these props, you can pass them to mutate functions like this:

const { mutate } = useDelete();

mutate(
    {
        resource: "products",
        id: 1,
    },
    {
        onError: (error, variables, context) => {
            // An error occurred!
        },
        onSuccess: (data, variables, context) => {
            // Let's celebrate!
        },
    },
);

Mutation Parameters

resource

required

It will be passed to the deleteOne method from the dataProvider as a parameter. The parameter is usually used as an API endpoint path. It all depends on how to handle the resource in the deleteOne method. See the creating a data provider section for an example of how resources are handled.

const { mutate } = useDelete();

mutate({
    resource: "categories",
});

id

required

It will be passed to the deleteOne method from the dataProvider as a parameter. It is used to determine which record to delete.

const { mutate } = useDelete();

mutate({
    id: 123,
});

mutationMode

Mutation mode determines which mode the mutation runs with. Mutations can run under three different modes: pessimistic, optimistic, and undoable. The default mode is pessimistic. Each mode corresponds to a different type of user experience.

Refer to the mutation mode documentation for more information →

const { mutate } = useDelete();

mutate({
    mutationMode: "undoable",
});

undoableTimeout

When mutationMode is set to undoable, undoableTimeout is used to determine the duration to wait before executing the mutation. The default value is 5000 milliseconds.

const { mutate } = useDelete();

mutate({
    mutationMode: "undoable",
    undoableTimeout: 10000,
});

onCancel

When mutationMode is set to undoable, onCancel is used to determine what to do when the user cancels the mutation.

const { mutate } = useDelete();

mutate({
    mutationMode: "undoable",
    onCancel: (cancelMutation) => {
        cancelMutation();
        // you can do something else here
    },
});

successNotification

NotificationProvider is required for this prop to work.

After data is fetched successfully, useDelete can call open function from NotificationProvider to show a success notification. With this prop, you can customize the success notification.

const { mutate } = useDelete();

mutate({
    successNotification: (data, values, resource) => {
        return {
            message: `${data.title} Successfully fetched.`,
            description: "Success with no errors",
            type: "success",
        };
    },
});

errorNotification

NotificationProvider is required for this prop to work.

After data fetching is failed, useDelete will call open function from NotificationProvider to show an error notification. With this prop, you can customize the error notification.

const { mutate } = useDelete();

mutate({
    errorNotification: (data, values, resource) => {
        return {
            message: `Something went wrong when getting ${data.id}`,
            description: "Error",
            type: "error",
        };
    },
});

meta

meta is used following two purposes:

• To pass additional information to data provider methods.
• Generate GraphQL queries using plain JavaScript Objects (JSON). Please refer GraphQL for more information.

In the following example, we pass the headers property in the meta object to the deleteOne method. With similar logic, you can pass any properties to specifically handle the data provider methods.

const { mutate } = useDelete();

mutate({
    meta: {
        headers: { "x-meta-data": "true" },
    },
});

const myDataProvider = {
    //...
    deleteOne: async ({
        resource,
        id,
        meta,
    }) => {
        const headers = meta?.headers ?? {};
        const url = `${apiUrl}/${resource}/${id}`;

        //...
        //...

        const { data } = await httpClient.delete(url, undefined, { headers });

        return {
            data,
        };
    },
    //...
};

dataProviderName

If there is more than one dataProvider, you can specify which one to use by passing the dataProviderName prop. It is useful when you have a different data provider for different resources.

const { mutate } = useDelete();

mutate({
    dataProviderName: "second-data-provider",
});

invalidates

invalidates is used to specify which queries should be invalidated after the mutation is completed.

By default, it invalidates the following queries from the current resource: "list" and "many". That means, if you use useList or useMany hooks on the same page, they will refetch the data after the mutation is completed.

const { mutate } = useDelete();

mutate({
    invalidates: ["list", "many"],
});

Return Values

Returns an object with TanStack Query's useMutation return values.
